Abstract

The invention is made up of a container made of plastic or metal. The upper part of the container is a storage unit for feed. At the bottom of the storage unit is a small opening in which rollers are located close together and are energized to let the food pass between them. The rollers are counter rotated to slowly turn and dispense the food onto a tray which will at a given weight, adjusted by a control level located in the back, dump the dry feed into a dish outside of the container. This process is triggerred by a timer that by electricity will actuate the motor driven rollers to allow them to pass the food into the tray.

As the tray is being measured, water is also being released, and if desired may mixed with the food. The water is at the same time also going into a separate water container for the purpose of drinking.

The invention is unique in solving the problem of leaving an unattended animal for periods of time where the animal would otherwise need human attention or would go without nourishment of food and water. Through his method the animal may be fed either dry or moistened food either once or twice a day, at the owner's discretion.

This invention has particular applicability for home owners who keep pets and for commercial enterprises with watch dogs on the premises during the occupant's absence especially for weekends, vacations, business trips, etc., and the invention has particular utility in regulating the quantity of an animal's daily food consumption. Itobviates the imposition and expense of having to relocate an anmial to either a friend's home or to a kennel. Frequently the expense of such relocation costs a lot of money and is an inconvenience. The invention also solves the problem for persons who are not able to care for animals but wish to have the companionship of an animal without the ability to be mobile to maintain the care of their pet.

Description

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to the field of animal feeding and care more particularly to the feeding of domesticated animals. It improves over the method of having to hand feed an animal or having a friend or neighbor tend a pet while the owner is unable to do so because of absence.

2. Description of the Prior Arts

So far as is known, the simple and improved automatic animal feeder described and claimed herein has not been known heretofore.

Prior inventions of this type have not been known heretofore. They have also not been known to solve the problem of feeding and watering an animal at the same time while the animal is unattended.

The improvement resides also in the fact that the food is sealed off from air and weather elements that could deteriorate from the state in which it was purchased and loaded into the holding container before release for feeding the animal.

The invention is also an improvement over the prior art that food can be measured out in quantities to suit the size of the animal that is being fed and it can be dispensed at different or desired times of day according to the needs of the animal.

Another improvement is that fresh water can be dispensed each time fresh food is released, where before a human hand has been needed to supply the water once or twice a day or leave a large container of water out for the animal. Food and water so dispensed frequently gets stale after a day.

Similar devices of this type need much more maintenance required by human hands and water must be supplied from an outside source where the present unit has both food and water self-delivered.

Prior inventions for feeding domesticated animals are of gravity feed types which can allow an animal to feed until all of the food is gone. This oftentimes will cause bloating of the animal and on occasion the animal will vomit. Prior systems have resulted in leaving the animal without additional food for later times or days to come.

This invention relates generally to an improved automatic, timed, adjustable quantity animal feeding device having the ability to dispense feed to unattended animals. It can dispense a predetermined quantity of feed commensurate with dietary requirements of the animal or animals of interest. Still another objective is to provide a means of ready and simple adjustment of the mechanism to the predetermined quantity of feed prior to leaving the animal(s) unattended. It improves the problems of leaving food unsealed to get spoiled from weather and having the problem of bugs such as flies, birds, ants and roaches from getting to the fresh food.

It has the means of supplying fresh water regularly with fresh feed all timed and measured by the size of the animal(s). It can regulate the feeding not to allow an animal to over eat causing sickness or doing without feed in days to come. It has generally solved the problem by a mechanism wherein dry feed is stored and dispensed at predetermined times daily and in selectable quantities and the invention is singularly applicable to home owners and commercial enterprises which keep pets and watch dogs on the premises during the occupant's absence for weekends, vacations, business trips, etc.

Therefore, from the foregoing, it should be understood that objects of this invention include; an improved method of feeding an animal(s) unattended automatically at predetermined times and in predetermined quantities by means of a container having the ability to store and dispense dry feed with fresh water supplied once or twice a day.

A further object of this invention is that it can hold feed of the dry type and of any size in current use. The feed is placed in the hopper in any quantity up to full. At the present time the drive motor is energized by AC or DC current and food is passed between two counter rotating, deeply soft, non-food crushing rollers collecting by gravity into the weighing tray, which when the preset weight is met, which is determined by adjusting a counter weight on a support shaft locked with a lock nut accessible through an access door located in the back of the unit, de-energizes the motor and drops the contents into the delivery chute where the food flows by gravity into the feeding dish. The mechanism then resets itself for the next cycle. During the drive motor energization period, the water control solenoid valve is also energized, allowing water to flow to the drinking water dish and to the feeding dish in quantities predetermined by the adjustment valves.

Another object relates also to methods for providing moistening water for the timed and predetermined quantity of food and as an alternate, a constant drinking water level rather than timed predetermined drinking water quantities.

Another object of this invention is to provide a constant water level in the drinking water dish by yet another means, when desired, and when a pressure water supply system is not available. This accomplished by the means of a removable sealed storage tank appended to the main structure with the tanks relatively small filler neck opening extending down deeply into the water drinking tank. This alternate technique is simpler, therefore, less costly and is suitable for who can handle the weight of the filled tank.

A further objective of this invention is to provide a constant water level in the drinking water dish, when desired, and when a pressure water supply system is not available. This is accomplished by a means of a suitably dimensioned water storage tank appended to the main structure with the passive float-type control valve mechanism contained in the storage tank member and which extends downward suitably far into the drinking water dish to provide float action.

These and other objects of the invention will become apparent from a study of the following disclosure in which reference is directed to the attached drawing.

These and other objects, features and advantages of the invention, as well as the invention itself, will become more apparent to those skilled in the art in the light of the following detailed description taken in consideration with the accompanying drawings wherein like reference numerals indicate like or corresponding parts throughout the several views and wherein:

FIG. 1 shows the plan view as seen from above with the adjustment access door open and without the storage hopper cover when the unit is in its normal upright position.

FIG. 2 is a side view of the assembly with the near side panel removed to show the internal mechanisms.

FIG. 3 is the front view of the assembly facing the feeding dish, and with the front panel partially removed to show the internal mechanisms.

FIG. 4 is a schematic diagram of the electrical control system.

Referring now to the drawings FIG. 1, FIG. 2 and FIG. 3 and FIG. 4:

One embodiment of this invention as shown in the drawings includes a structure with a storage hopper 18 with access from the top by removal of the weather cover 17, and with the feed containment maintained by the back slant plate 7, the side slant plates 8 and 16, the front slant plate 9, and the two rollers 11 and 12. Although the weight of the food tends to rotate the rollers in the direction of the arrows in FIG. 3 and the idler roller 11 is free to rotate, drive roller 12 is not, due to the gearing ratio in the drive motor 13.

Adjustment of the timer for time(s) of day of feeding, adjustments of the counterweight of quantity of food at each feeding, and adjustments of water quantity for food moistening and for drinking are made through the access opening 23 available when access door 4 opens its hinge 5 through arc 2.

The dispensing cycle is initiated when the adjustable timer 19 energizes the drive motor 13 circuit through the normally closed contacts of relay 20.

Drive roller 12 now rotates in the direction of the arrow shown in FIG. 3 engaging food particles which depress equally into the surfaces of the drive roller 12 and the idler roller 11 causing the idler roller 11 to rotate in the direction of the arrow in FIG. 3. By this action, the food passes between the rollers, dropping onto the weighing tray 29 until the total weight of tray and feed exceeds the counterweight 21 as adjusted on its support shaft and locked in place by lock nut 22, accessible through access door 4 and opening 23.

At this point, weighing tray assembly 29, rotating on its shaft 28 and supported by the chute guides 27, immediately releases limit switch 31, whose normally closed contacts have been held open by virtue of the position of the weighing tray 29, during the quiescent mode of the cycle. Closing of the normally closed contacts of limit switch 31 now energizes the relay 20 coil which opens its normally closed relay contacts, de-energizing the motor 13 circuit and simultaneously locking relay 20 in the energized position through its normally open contacts, thereby, holding the motor 13 circuit de-energized.

The weighing tray assembly 29 upon rotation under load of its food content, by virtue of the position of its center of gravity with respect to its center of rotation, rotates until it contacts the chute surface 26, drops its entire content and returns to its quiescent position. This action again opens the normally closed contacts of limit switch 31 which will then allow the relay 20 to drop out and to close the normally closed contacts in the motor 13 circuit at the time that timer 19 de-energizes the system prior to the initiation of the next cycle. The dropped food quantities, directed by chute guides 27 flows by gravity down chute surface 26 through chute exit 32 into feeding dish 33.

Simultaneously during the period of drive motor 13 energization, solenoid valve 6 is energized permitting water from water inlet 3, (garden hose or hand piping) through water solenoid valve 6 through adjustment valve 24 and line 34 to drinking water dish 1 and through adjustment valve 25 and line 35 to feeding dish 33. The adjustment valves are accessible through access door 4 and opening 23.

The rollers 11 and 12 rotate on their own individual shafts supported and positioned by the aft shaft support member 15 attached to aft slant plate 7 and front shaft support member 10 attached to the front slant plate 9.

Drive motor 13 is coupled only to the drive roller 12 and is supported and positioned by motor support member 14 attached also to the aft slant plate 7.

The embodiment of the structure and mechanism is not to be construed as limiting to the configuration displayed wherein shown are four sides of equal rectangualr size and shape. Economies of materials and fabrication could dictate a more efficient use of structural members and component positioning, reshaping the geometry of the structure without altering the objects of this invention.
